It is already at 40 gw installed power and has maintained a 25 percent growth rate for about 10 years. That is doubling every 3 years. The only limiting factors, are Greenpeace complaints that they shred birds, and the fact you can't build them within site of land owned by the Kennedys or other "Limousine Liberals".
Just think, if the windmills are strategically placed in the path of migratory birds, and a system is devised to capture and process the bird fragments, we could have a dual fuel plant.
Just a thought. ; )
I hate windmills (except for small ones for individual farm/ranch generation). The hundreds that are typically put up on mountain tops are a blight on the horizon and do more than their share of bird killing. The eco-nazi's, in their hatred of fossil and nuclear fuels, are oblivious to the downside of this "green" technology.
